Ahrefs Alerts is three separate tools sharing one name, and only one of them is a monitoring product. Backlinks, new keywords and mentions each answer a different question, and each deserves a different decision.
Switch all three on for your own domain and you’ll generate a steady stream of email that you stop opening inside a month. That isn’t a fault in the tool. It’s what happens when three jobs get treated as one setting.
Here’s what each one watches, which ones are worth the inbox space, and the question none of them can answer.
What the Three Alerts Watch
They sit in the same menu and behave nothing alike.
| Alert | What it watches | The job it’s good at |
|---|---|---|
| Backlinks | New and lost links to any site or URL | Watching competitors rather than yourself |
| New keywords | Keywords a domain, subfolder or URL starts ranking for | Reporting, and catching a page that drifted |
| Mentions | New pages matching a search query you write | Finding unlinked mentions worth reclaiming |
Note the second column on the backlinks row. You can point it at any domain, not only your own, and that single detail is what makes it useful.
Why the Word Alert Oversells It
It oversells because nothing fires when a page is published. The alert fires when Ahrefs crawls that page and its index updates, which can be days later.
That gap is the same one behind a link you paid for that hasn’t turned up yet. We covered it in a backlink that hasn’t appeared.
An alert doesn’t shorten the wait. It tells you when the index caught up.
Judge the lag against the job
For link reclamation the delay costs you nothing, because a mention published last Tuesday is still reclaimable this Friday. For anything resembling a communications emergency it’s useless, and reaching for it will leave you finding out last.
The Lost Backlinks Alert Will Cost You the Most Time
It’s the one that fires most and means least. A link reported as lost often reflects the state of the last crawl rather than an editor removing anything.
A page that timed out, a temporary error or a redirect in progress can all produce the same notification. Open the live page and search for your URL before you email anybody about it.
Run that check a few times and you’ll build a feel for which of your placements genuinely churn, which is worth more than the alert itself.
How to Make the Mentions Alert Earn Its Place
You’ll get the most out of this one, and it’s also the one that arrives useless by default. Four settings decide which.
Take your own domain out first
You can exclude domains from the alert, and your own site belongs at the top of that list along with your subdomains. Exclusions quietly decide what a report means, which is the argument in our piece on what your exclude filters decide.
Search for more than the brand name
The query accepts operators, so one alert can cover the brand plus its common misspellings, product names and the people who speak for you. Our walkthrough of finding unlinked mentions in Content Explorer lists the mention types most teams never search for.
Decide between title and content
You can match the query in a page title, in the body, or in both. Title matching gives you pieces that are about you, and content matching gives you passing references, which are usually the reclaimable ones.
Take the weekly digest
Daily and weekly are both available. Weekly wins for most brands, because a batch you read is worth more than a drip you archive.
What None of the Alerts Can See
All three read a crawled web index, so the boundary is the same for each of them.
- Pages behind a login. Private communities, most social platforms and closed forums stay invisible.
- Spoken and video mentions. A podcast or video naming you leaves nothing for a text query to match.
- Answers an assistant writes about you. Text generated for one person was never a page.
The last one is the gap that has grown. A model describing your product to a buyer produces no URL to crawl, so no crawler-based alert will ever catch it. That’s why alerts built for AI answers are a separate instrument rather than a setting.
What We’d Switch On
Three decisions, and one of them is to leave something off.
- Mentions on your own brand: yes, weekly, with your domain excluded and misspellings included.
- Backlinks on your competitors: yes, because their new links are your prospect list.
- Backlinks on your own site: only while a campaign is live and you’re checking placements.
- New keywords: skip it as an alert and read the same data in a report instead.
That leaves two live alerts rather than five, and two you’ll still be reading next quarter.
Frequently Asked Questions
Is there a limit on the number of alerts
Enough that the limit won’t be what stops you. Restraint is the real constraint here, because an inbox with fifteen alerts in it is an inbox nobody reads.
Why did I get a lost backlink alert for a link that’s still there
Because the report reflects the last crawl rather than the live page. Check the page yourself, and treat the alert as a prompt to look rather than as a finding.
Does the mentions alert find social media posts
Not reliably. It reads crawled pages, so anything behind a login or inside a closed platform sits outside what it can match.
Should I use Google Alerts as well
They index differently, so running both catches more than either does alone. Expect duplicates, and expect neither to see what an AI assistant tells a buyer.
Is a backlinks alert on a competitor worth more than one on my own site
Usually, yes. Your own new links are ones you already know about, and theirs are sites that have recently proved they’ll link to something in your subject.
Set Up Two, Not Five
The alerts are worth having once you stop expecting them to be a monitoring system. Point the backlinks alert at your competitors, spend ten minutes writing a real mentions query, and let the rest stay off.
